RSS is a format for syndicating news and the content of
news-like sites, including major news sites like Wired,
news-oriented community sites like Slashdot, and personal
weblogs. But it's not just for news. Pretty much anything
that can be broken down into discrete items can be syndicated
via RSS: the "recent changes" page of a wiki, a changelog
of CVS checkins, even the revision history of a book. Once
information about each item is in RSS format, an RSS-aware
program can check the feed for changes and react to the
changes in an appropriate way.

Sports Blogs is a RSS-aware website.. It goes out to each
of these blogs on a regular basis and checks to see if new content
has been added.

an application that I have been building at http://rss.sportsblogs.org/makeRSS.php
to make your Blogger blog have an RSS feed.

Movable Type - Movable Type is another
popular blogging application for more technically inclined people. They provide
RSS syndication in their application. From their
